Issue about the generated occupancy map.

You just need to flip the visualization vertically. The mapping code logic is correct.

No module named 'env.habitat.habitat_api.habitat'

This might be the same issue with python 3.6 as mentioned in this thread: https://github.com/devendrachaplot/Neural-SLAM/issues/1

Distorted output

The output looks correct to me.

ClassNLLCriterion.cu:105: void cunn_ClassNLLCriterion_updateOutput_kernel(Dtype , Dtype , Dtype , long , Dtype *, int, int, int, int, long) [with Dtype = float, Acctype = float]: block: [0,0,0], thread: [0,0,0] Assertion `t >= 0 && t < n_classes` failed.

This seems to be an issue with your CUDA or pytorch installation and does not seem to be related to the Neural-SLAM code.

Observation shows black images/screen

The code does not require the 3DSceneGraph to be built as it does not require access to ground-truth semantics. Could you try saving the images obtained from habitat directly here:...

Issues installing detectron 2

Please open this issue on the detectron2 repository.

single GPU error

Could you verify that you have installed the correct older versions of habitat-sim and habitat-api as described in the README?
